Specification of Illetters Patent. Application filed-Jul 19, 1911. Serial No. 639,447.;

Patented N 0v. 25, 1913.

To all whom it may concern:

Be it known that L'GUSTAF VJ. Mnonus, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, haveinvented certain new and pervious to moisture, pliable, andwvitha surface not liable to crack or peel oif and having a fresh, glossy appearance.

With these objects in View, the invention consists in a composition-formed of the following ingredients and proportions, co npounded and used in the manner hereinafter explained. I take fifteen parts by Weight of raw linseed oil and one part o-flow grade rubber, and boil the same together slowly for four hours, stirring constantly. The mixture is then removed from the fire and approximately one part of White drier, or equivalent, is added and thoroughly incorporated. After cooling the mixture may be applied to the fabric to be treated with a brush. The white drier employed is made by boiling sugar of lead in raw linseed oil and thinning with turpentine or benzin.

The fabric is provided With a coating upon both sides and allowed to dry for about twenty-four hours whereupon another coat "maybe added usually upon the outside only.

It Will not injure theinost delicate fabric and Will render the same perfectly watertight for an indefinite-period.

It is particularly adapted to the preparation of water-proof clothing, its pliability and lack of susceptibility, to heat or cold causing it tobe Well fitted for personal Wear.

It isinexpensive in cost of materials and manufacture. The grade of rubber used may vary with the quality of product-sought but the cheaper grades, as recovered rubber,

such as is obtained from old rubber boots and the like, issullicient for the purpose.

The composition may be-made in "any color desired by the use of correspondingly.tinted rubber or the use of rubber of a neutral color and the addition of a suitable pigment.

What- I claim as my invention, is-

A liquid Water-proof surfacing composi t-ion consisting of fifteen parts by weight of raw linseed 011, one part by Weight of low grade rubber and one part suitable White drier.
